GEORGE ELLIOT PERRY, 0F CHICAGO, ILLINOIS.

TIME-STAMP.

T0 all whom t may concern Be it known that I, GEORGE ELLIOT PERRY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Time- Stamps, of which the following is a speciflcation.

My invention relates to improvements in time stamps, and more particularly in some of its features to small, portable stamps adapted to be carried in the hand and in which the impression parts are inked from an ordinary inking pad.

Among the general objects of my invention is to provide a construction which is eflicient, simple, cheap, and durable.

Among the objects specifically sought are relative smallness of size and convenience of arrangement of parts of the stamp, so that it may be readily manipulated and held by three ngers with the stamp underlying the heel of the hand, so that the index finger and thumb may be used in asserting mail, or the like.

Another object is to provide such construction that the horological motor is amply protected against undue shocks and jars, and is disposed for easy winding, setting, and regulation.

A further object is to insure a clean, sharp impression from the time-impression means, however carelessly the stroke of the stamp may be made, and further to prevent the horological motor from being subjected to any retardation or drag when the printing base of the device rests upon or is pressed down on a supporting surface, the arrangement provided by my invention being such that upon each stroke of the stamp the time impression devices are momentarily brought into printing contact with the subjacent surface as a result of impact as distinguished from steady pressure.

Another` object of my invention is to provide a construction in which the assembling in manufacture is particularly simple and inexpensive, and in which the interconnection between the various individual parts is such that close interfitting is practically unnecessary.

In the drawings, wherein I have illustrated a practical embodiment of my invention; Figure l is a perspective view with parts broken away showing the complete stamp; Fig. 2 is a central section there- Specification of Letters Patent.

through with parts in elevation; Fig. 3 is an enlarged section on line 3 3 of Ilig. 2; llig. il is a perspective detail of a. coupling connection and Fig. 5 indicates the character of the impression made by the stamp.

In the drawings, l() indicates in general the stamp frame, of any suitable construction, preferably encased, and therefore, hereinafter referred to as a casing. Such casing comprises telescoping upper and lower casing sections 1Q and 13 formed of thin sheet metal, connected with a stiff top plate l-l and base plate l5, for adequate strength. The casing may conveniently be made substantially square in form, the true frame including posts 16 extending through the corners of the casing suitably fastened to the top plate let, and having the base plate l5 secured to their lower extremities as by screws 17, so that no weight is carried by the thin casing walls. Upon the base plate is secured an impression member 1S preferably of rubber, or other resilient material, preferably bearing more or less printing surface including, in the structure shown, an annular clock dial lf). T his impression member I will term the impression base, its lower surface being adapted to strike the surface to be printed and to define the printing plane. A handle 2O of convenient design to fit the heel portion of the hand is connected to the top of the frame or casing, preferably in such manner as will permit the universal angular displacement of the handle relative to the top of the casing or to the printing plane. The specific construction shown provides, in attachment to the top plate let, a cup 21 in which is seated a block of rubber 22, overlain by an inverted cup 23, secured to the handle 2O by a screw 2l. Through an axial bore in the rubber and appropriate openings in the cups pass two hook members 25 interconnected to form a fieXible joint at 2G, substantially centrally of the rubber body 22, one of said members preferably having a threaded stem receiving a nut 27 overlying cups 93, whereby the two cups 2l and 2B may be drawn more or less toward each other and the tension upon the rubber body `correspondingly lixed as desired in the assembling of the parts.

30 indicates in general a horological motor preferably in the form of a watch provided with a winding and setting stem 8l. The motor is supported in the casing in cushioned 36 carries a U-sha-ped strap 90 through the legs of which slides horizontally a bar 91 having fixed to its center at right angles to its axis an arm 92, the downwardly extending fingers 93 at the extremity whereof engage alongated notches 95 in the upturned legs of a U-shaped yoke, 96 secured to the stem G9 of the minute time-impression part.

In the organization of the structure the parts are so proportioned that the printing surfaces of the impression parts 62 and 66 stand normally in a plane considerably above the impression plane 19 of the impression base 18. Now it will be apparent that when the stamp is struck, even lightly, upon an inking pad or surface to beprinted, the impact throws downward the floating platewhich through yielding connections L12 carries the weight of themotor-against the tension of the light spring 42, so bringing the time impression and kdate impression surfaces down to the level of the printing plane 19. As soon as the springs overcome the momentum of the motor, the parts are instantly spring-returned to initial position. Thus the time impression surfaces make only a momentary contact with the inking pad or the surfacer to be printed, and produce a clear, sharp impression, regardless of whether or not the printing base is struck against the surface to be printed squarely or in careless, slipping fashion. Also it is practically impossible to make an impression or to ink the stamp by imposing any amount of pressure upon the casing or the handle, the time impression devices being carried too high above the surface 19 of the printing base 1S to be brought into contact with the surface to be printed by any mere compression of the resilient pad 1S. In point of fact, the pad 18 can be made rigid, as by the use of metal in lieu of rubber, if desired, for example, by reason of the use of the stamp in an atmosphere where the rubber would not last. In any event the construction shown insures clearness of the time-impression without retardation 'of the motor.

I have herein described specifically a stamp which I have found in practice to be efficient and satisfactory. It will be observed that the structure contains no parts diilicult or expensive to manufacture; that it enables the use of an ordinary, inexpensive watch movement as the horological motor, that it facilitates asse1nbling,-as substantially all of the detachable parts are simply strung upon the posts for guidance thereby-and that it makes substantially impossible the injury of the mechanism or the disturbance of the connection between the motor and time impression devices by any amount of rough usage.
